nu·tri·ent

noun

a substance that provides nourishment essential for growth and the maintenance of life.

Turmeric isn't a nutrient. I'm talking about fats, sugars, proteins, which your body hoards every bit of no matter how much is eaten in one meal or spaced out. Of course there are exceptions like if you drink a gallon of oil and you get oily diarrhea, but a normal person absorbs all the calories and energy that is available from the food they consume.

Iron has its own regulation system of absorption and excretion, based on the iron status of the individual. If only we had those checks and balances on our caloric intake!

Yes, turmeric isn’t a nutrient, it’s a spice made up of nutrients.

Believe it or not vitamins and minerals are nutrients.

In nutrition science vitamins and minerals are generally referred to as micronutrients whereas fats, sugars, proteins are referred to as macronutrients.

And no macros are not all absorbed the same. As a general rule the longer someone’s intestines the more macro absorption they will have than someone with a shorter intestinal track. As I have already suggested digestive enzymes play a role, so if someone ate black pepper as I suggested before, that will secrete more digestive enzymes allowing for more absorption of calories and macros. There is also gut bacteria (microbiome) take for example the study of African twins where one is healthy and the other malnourished, where it was determined the malnourished twin with the same diet wasn’t absorbing the same amount of nutrients as the healthy twin because of the difference in their microbiome.

I'm sorry but you really don't know what you are talking about. I think you have accumulated a lot of repeated information from blogs and shoddy websites instead of from science.

This is the only reference I see in pubmed for calories and black pepper and it says black pepper raises the resting metabolic rate, nothing about absorption. And it shows black pepper reducing obesity which would be the opposite of what you are describing.
